The endgame is nearly winning for White with a development advantage and better pawn structure. Black has trouble getting the bishop into play, and the backward d-pawn is a long-term weakness.
13... b6c5  14. a1d1  14... g6e5 A bad move, since the knight will soon be attacked by f4 and White remains with a firm grip on the dark squares. 15. d3d6  15... c5d6
